To investigate the parameters estimation of Frank coded signal in noncooperative condition, an averaged cyclic periodogram based cyclic spectral features estimation algorithm is proposed. The connection between signal parameters and cyclic spectral features is utilized to estimate the key parameters of Frank coded signal. The amount of calculation and the process of the algorithm is given and analysed. The normalized RMS error （NRMSE） of estimation is measured to analyse the influence of the noise on parameters estimation and verify the validity of the algorithm.
